14 Claims.

My invention relates in general to printing devices. It relates more inparticular to a printing attachment adapted to supplement a conventionaltype of printing press to secure a color effect.

Recently there has beenv a great demand'on the part of advertisers forcolor in newspapers. Some newspapers have installed full color equipmentand others have modified existing presses to make it possible toprint'in color. I have found, however, that printing an entireadvertisement in color is not necessary to make the advertisement standout, but any type of color may be used which will have the effect ofattracting attention of the reader. The color may be employed either inthe margin, down the center of the page, or in any other place on thepage, depending upon the set up, which will have the desired attractingprope yg The principal object of my present invention is the provisionof mechanism which can be used for this purpose. I

Anotherobject is the provision of a printing attachment which can beused as an adjunct with substantially any type of printing equipment inwhich the paper is moved linearly.

Another object is the provision of improved inking means in auxiliaryprinting apparatus.

Another object is the provision of an improved type of printing rollerparticularly adapted for use in auxiliary press equipment.

Another object is the provision of an auxiliary printing device whichwill be of substantially universal adjustment.

Other objects and features of the invention will be apparent from aconsideration of the following detailed description taken with theaccompanying drawings, wherein 'Fig. 1 is an elevational View showingone embodiment of the device of my invention;

Fig. 2 is a plan view thereof; Fig. 3 is a sectional View taken on theline 33 of Fig. 2;

. Fig. 4 is a transverse sectional view taken on the line 4-4 of Fig. 1;

Fig. 5 is a fragmentary, sectional view partly shown in plantoillustrate features of construction;

Fig. 6 is a fragmentary plan view;

Fig. '7 is a slightly enlarged sectional view taken on the line l-'! ofFig. 2; and

Fig. 8 shows a fragmentary section of a newspaper illustrating onemanner of using the de- 7 Vice of my invention.

According to the general features of my invention, Iv provide a rollerhaving a composition to engage amoving article such as a moving strip ofpaper with suitable friction. Composition'rubber with the printingindicia in relief is very satisfac- 60' tory fortheiipurpose. Inksupplying mechanism is provided, and the ink supplying mechanism isoperated by power derived from the movement. of the printing roller bythe paper. The roller and ink supplying mechanism are preferablyprovided as a single unit and the unit itself is designed to be mountedin any position on any type of press or equipment over which the paperis moved. Lateral adjustment is provided to control the position on thepaper at which the roller will print, and a further adjustment isprovided to control the impression against the paper. By means of thislatter adjustment, the roller may be taken out of contact with the paperor the firmness of the impression adjusted as desired.

The main purpose of the mechanism is to print indicia runninglongitudinally of the paper. The position is conveniently along one orboth margins, along the center of the page, or in any other suitableposition depending upon the character of the advertisement. In Fig. 8,the term $-Day would be printed by the mechanism of my inventionwhilethe remaining portion of the page would, for example, be the ordinarynewspaper print. As an example, the newspaper print would be in theconventional black while the print $-Day might conveniently be in red.Any

type of indicia can, of course, be used. In an automobile advertisement,for example, the in dicia printed by my mechanism might be a series ofsmall automobiles. Naturally, it is impossible to give even arepresentative number of illustrations, as the particular advertisementor advertisements being featured would determine the oharacterof indiciato be used to attract the reader. While usually the mechanism of myinvention would be adjusted to print a strip running vertically on thepage, by proper positioning of the printing roller it may under someconditions be made to print laterally of the page. In bringing thisabout, the mechanism of my invention may, for example, be mounted onv afolder, that is, the type of machine used in some plants for folding.

Referring now to the drawings, the embodiment of the invention thereshown comprises a main frame iii which is adjustable along a rod H. Theframe with the hinge portion 52 is adapted to engage around the rod Hand at any selected position to be clamped thereon by means of a capscrew E3. The rod ii is made out of round to prevent the frame fromtipping. In the present form, I show a key it engaging in a keyway ofthe frame portion ll.

Above the main frame I support a vessel !6 which also comprises part ofthe frame. This vessel is disposed in a channel formed in the top of themain frame, and a pair of strips ll (Fig. 4) screwed to the main frameengage over the top of shoulders provided on the vessel It. Thisvesselis adapted to carry ink l8 which is 'mediate its ends at 42.

. U-shaped frame at 59. low the arm 51 are employed to regulate theposition of the Ushaped member with respect fed thereto from an invertedbottle is. The ink the cup barometer and in a manner well under stoodthe level of ink in the vessel I8 is maintained by this arrangement.

threaded into a boss formed'in thevessel to provide for adjustment bymeans of which the height of the ink in the open portion of the vesselcan be controlled. v t

A roller supporting frame 22 is secured to one end of the vessel 16 bycap screws 23; Thisframe has one arm 2 which carries an integral houseing 26 (Fig. 5) Within which housing a shaft 21' is rotatably journaled.Preferably I'eniploy' a ball bearing support for the shaft 21', theball.

29 on its outer periphery. The hub of the wheel 28 extends axially andis adapted to receive a nut 35 by means of which a plate 32 is clampedagainst. the printing band. The wheel 28 has.

an annular flange 28a whichco operates with the plate 32to hold theprinting band in fixed position. The entire assembly including the wheel28, the printing band 29, and plate comprises the printing roller. 7

Ink is delivered to the printing roller from a transfer rollerv 33. Thistransfer roller in turn receives ink from an oscillating ink drum 34and.

the latter is supplied by a ductor roller 36 which picks the ink up fromthe; vessel l5. These rollers are operated by the printing rollerthrough mechanism which will now be described.

The shaft 21 has secured thereto a worm 3'8 meshing with a worm gear 38carried on a vertical shaft 39.journaled in a portion of the frame.

An eccentric boss 39 carried by the worm gear 38 engages in a slot in.an arm 4i pivoted inter- This arm M has a, pin 13 at its free endengaging in an annularslot a roller M; This roller is pinned to shaftwhich carriesv the ink drum 34. It is, moreover, .journaled and slidablysupported in the frame so that the resulting oscillating motion impartedto it through the eccentric 39 and the arm l will be effective todistribute the ink uniformly and evenly over the transferroller 33.

The ductor roll 35 is carried ona shaft i'l loosely carried on the endsof a generally U- shapedmember 48 pivoted to the frame by cap screws 39.This member is normally held upwardly by a tension spring 5i. Itisadapted, however, to be moved downwardly aboutits pivot so as to projectthe ductor roller into an open portion of the vessel It to pickup theink. For

imparting the necessary movement to the U- shaped member 58 to obtainthis function, I provide a face cam 52 on the worm gear 38. Thisengagesunder a roller 53 to raise it, and the roller is journaled on anarm 5 pinnedto 'a shaft 56 journaled in a portion of the frame. Theopposite end of the shaft 58 carries an arm 5?. The arms 56 and 5? takentogether func tion somewhat as a bell crank in that when arm 5% israised through the cam and roller, the arm 5i is lowered. The outer endof arm 5'? is aper tured to receive a toggle link 58 pivotedto the Nuts"6| above and be to the arm 5'! and so control the movement of theU-shaped arm.

The neck. of the bottle l9 extends into a support. 2| which is 1 havethe roller 64 to. bear against.

ing roller through friction. In the position which 1 is supported in thebottle 19 on the principle of V the ductor has in full lines, which isits normal ductor roller projects into the ink. This is furtherprevented by a screen 62 which sets over the top of the open space intheve'ssel It. This screen has the function of arresting any rotarymovement which the ductor roller may still have and also-of limiting theinsertion of the duct-or roller into the ink. This makes itv unnecessaryto adjust the movement of the ductor roller and.

height of the ink within extremely close limits.

'Sincethe ductor roller shaft is'only. loosely car-- ried in thevertical slots in the U-shaped member, the movement of the ductor rollercan be arrested by the screen independent of how far the U-shapedmemberitself will move.

As previously described, thefprintin'g. roller is.

adapted to engage a moving article in order to print. onto suchmovingarticle the indicia carried in relief on the. periphery of theprinting.

roller. In the drawings, I show a strip of pa-.

per running between a pair of idler rollersa and S6. The position ofthe-printing roller is such that it can engage the, paper and stillunderstood that this is a more or. less schematic.

It willbe V showingifor the purpose of illustration.

printing roller may engage the paper. at any position and any type ofbearing surface may be provided at the point of contact. For exam-- ple,a fiat, stationary surface over which the paper moves can be used withsatisfaction; In order to adjust the impressionv of the print-j ingroller, I provide an arbor 61 secured'to the main frame IE! and having aforked portionadapted toengage inan annular groove or channel in anadjusting nut 68/ This adjusting nut is threaded on a bolt 69- secured.to the vessel portion l6. By turning. the adjusting nut 68, the vesselportion with'the attached framemembers and apparatus mounted thereon canbe moved toward or away from the paper. A'lock nut i l is: i

also provided to maintain'theimpression constant.

.I have previously noted that" the device of my invention may bemounted-to operate onthe moving paper at substantially any point and onany type of printing device in which the paper is moved continuously.Accordingly, I show por -N tions of the press frame 12 and I3 brokenaway to conserve space. The rod H which is also. broken away to conservespace is shown attached by suitable means to the frame members.
